Question, could it just be missing a ball? Meaning only two are loaded in the machine?
Honestly, I am on the east coast by Philadelphia and pin prices are crazy here too with all the collectors between NYC and DC and I wouldnt pay more thank 1k for that machine. If the cabinet is nice and the PF is great, maybe 1200 but thats it.
Check the supercharger on that baby. If it doesnt work, that could be a good amount of $$$ to repair.
Good luck. Its an awesome game. Report back.
